Description
- The present invention contains subject matter related to Japanese Patent Application JP 2005-192734 filed in the Japanese Patent Office on Jun. 30, 2005 and Japanese Patent Application JP 2005-233587 filed in the Japanese Patent Office on Aug. 11, 2005, the entire contents of which being incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a graphical user interface device, an operating input processing method, and a two-way communication apparatus. Particularly, the present invention performs only changing of a selectable part of a graphical user interface and selection of a selectable part in response to a user operation, and when a part is selected, performs a process corresponding to the selected part, thus enabling for example a two-way communication using a common graphical user interface in either of a case of using a pointing device and a case of using a keyboard.
- 2. Description of the Related Art
- A system that makes it possible to perform two-way communication while viewing the face of another person by transmitting an image picked up at each of two points at a distance from each other to the other point via a network and displaying the image, for example a videoconferencing system is spreading.
- Such a videoconferencing system uses a graphical user interface that displays icons showing personal information of conference attendees in a conference room (first conference room) of an own self and a conference room (second conference room) of another person and icons showing devices in the conference room of the own self and the conference room of the other person before a conference is started, as in Japanese Patent Laid-open No. 2001-331429, for example.
- When the graphical user interface is used, a pointing device, a keyboard, a remote control device having similar functions to those of the pointing device and the keyboard, and the like are utilized as user operation inputting unit.
- When the keyboard is used, information corresponding to a key operation, for example a character, a number, a symbol or the like can be input. It is also possible to move a cursor on a screen according to a key operation, and indicate or select a desired part of the graphical user interface. When the pointing device is used, on the other hand, while it is possible to move a pointer on the screen, and indicate or select a desired part of the graphical user interface, a character, a number, a symbol or the like cannot be input directly from the pointing device.
- Thus, when the pointing device and the keyboard are made usable, a graphical user interface supposing the use of the keyboard and a graphical user interface supposing the use of the pointing device are provided separately from each other. In addition, supposing the use of both the pointing device and the keyboard, a graphical user interface is configured with a mixture of parts to be operated by the pointing device and parts to be operated by the keyboard.
- However, when a graphical user interface supposing the use of the keyboard and a graphical user interface supposing the use of the pointing device are provided separately from each other, the number of man-hours for designing the graphical user interfaces, cost and the like are increased. If parts to be operated by the pointing device and parts to be operated by the keyboard are mixed with each other, some parts cannot be operated when only one of the pointing device and the keyboard is used.
- Accordingly, the present invention provides a graphical user interface device, an operating input processing method, and a two-way communication apparatus that make it possible to operate parts of a graphical user interface similarly when using either of a pointing device and a keyboard.
- In a graphical user interface device, an operating input processing method, and a two-way communication apparatus according to embodiments of the present invention, one of changing of an indicated part and selection of an indicated part is performed selectively in response to a user operation, and a process corresponding to a selected part is performed. The state of parts is limited to states corresponding only to changing of an indicated part and selection of an indicated part. The process corresponding to the part does not need user operations of other than change and selection.
- According to embodiments of the present invention, one of changing of an indicated part and selection of an indicated part is performed selectively in response to a user operation, and a process corresponding to a selected part is performed. Therefore, parts of a graphical user interface can be operated similarly when either of the pointing device and the keyboard is used as an operation input unit for receiving a user operation, and thus the two-way communication apparatus can be operated or set easily. In addition, since a graphical user interface supposing the use of the pointing device and a graphical user interface supposing the use of the keyboard do not need to be provided individually, graphical user interface design can be performed efficiently.
- The above and other features and advantages of the present invention will become apparent from the following description when taken in conjunction with the accompanying drawings which illustrate preferred embodiments of the present invention by way of example.

FIG. 1 is a front view of a two-way communication apparatus 10 used in a system for performing two-way communication, for example a videoconferencing system. - An
image pickup unit 11, adisplay unit 12, amicrophone 13, aspeaker 14 and the like are provided integrally with each other in the two-way communication apparatus 10. In addition, though not shown in the figure, a codec, a communication unit and the like are included in the casing of the two-way communication apparatus 10. This two-way communication apparatus 10 allows operation change, various settings and the like using a graphical user interface. -
FIG. 2 shows a configuration of the two-way communication apparatus 10. Theimage pickup unit 11 is formed using a CMOS image pickup element, a CCD image pickup element or the like. Theimage pickup unit 11 generates a video signal SVcam of a picked-up image, and then supplies the video signal SVcam to an A/D converter unit 21. In addition, theimage pickup unit 11 has an image pickup direction varying function and a zoom function to perform a tilting operation, a panning operation, and a zoom ratio changing operation on the basis of a control signal CT from acontrol unit 50 to be described later. - The A/
D converter unit 21 converts the video signal SVcam into a digital video signal DVcam. The A/D converter unit 21 then supplies the video signal DVcam to avideo codec 23 and a scaler/OSD (On-Screen Display)unit 24. Thevideo codec 23 generates a video encoded transmission signal NTv by encoding (compressing) the video signal DVcam. Thevideo codec 23 then supplies the video encoded transmission signal NTv to acommunication unit 40. In addition, thevideo codec 23 decodes (decompresses) a video encoded received signal NRv supplied from thecommunication unit 40. Thevideo codec 23 supplies a video signal DVr obtained by the decoding to acapture unit 25 and adisplay driving unit 28. - The scaler/
OSD unit 24 performs a process of changing the size of the image based on the video signal DVcam and a still image stored in animage memory unit 26 to be described later and a process of generating an image on the basis of character information and color information on the basis of the control signal CT from thecontrol unit 50 to be described later. In addition, on the basis of the control signal CT from thecontrol unit 50 to be described later, the scaler/OSD unit 24 for example generates a top screen, an address book screen, various menu screens, and a communication screen when communication is performed with an image of a person at another end of the communication being displayed by using the generated image, the image based on the video signal DVcam, the still image, an image changed in size, and the like as occasion arises. Further, the scaler/OSD unit 24 supplies a video signal DVm of various screens such as menu screens and the like to thedisplay driving unit 28. - The
capture unit 25 captures the video signal DVr supplied from thevideo codec 23, generates a still image signal DVs, and then supplies the still image signal DVs to theimage memory unit 26. Theimage memory unit 26 has a capacity for storing a large number of still image signals. Theimage memory unit 26 stores the still image signal DVs supplied from thecapture unit 25. In addition, theimage memory unit 26 supplies the still image signal DVs stored therein to the scaler/OSD unit 24. - An
input terminal 15 is to input an image generated by a computer device or the like (not shown). A video signal DVp input from the computer device or the like to theinput terminal 15 is supplied to an inputimage processing unit 27 and thedisplay driving unit 28. - The input
image processing unit 27 is connected with thecommunication unit 40. The inputimage processing unit 27 supplies the video signal DVp from theinput terminal 15 to thecommunication unit 40. In addition, the inputimage processing unit 27 generates a new video signal DVn on the basis of the video signal DVp supplied from theinput terminal 15 or a video signal DVq supplied from thecommunication unit 40. The inputimage processing unit 27 then supplies the video signal DVn to thedisplay driving unit 28. - The
display driving unit 28 selects one or a plurality of video signals of the video signal DVr supplied from thevideo codec 23, the video signal DVm supplied from the scaler/OSD unit 24, the video signal DVp supplied from theinput terminal 15, and the video signal DVn supplied from the inputimage processing unit 27 on the basis of the control signal CT supplied from thecontrol unit 50. Thedisplay driving unit 28 generates a driving signal DR on the basis of the selected video signal (s). Thedisplay driving unit 28 then supplies the driving signal DR to thedisplay unit 12. In addition, the display driving unit for example changes the size of an image based on the selected video signal(s) as occasion arises. - The
display unit 12 is formed by using a liquid crystal display element, a plasma display panel, a cathode-ray tube or the like. Thedisplay unit 12 performs display operation on the basis of the driving signal DR supplied thereto. Thedisplay unit 12 displays an image on the basis of an instruction from thecontrol unit 50. - The
microphone 13 supplies a generated audio signal SAmic to an A/D converter unit 31. The A/D converter unit 31 converts the audio signal SAmic into a digital audio signal DAmic. The A/D converter unit 31 then supplies the audio signal DAmic to anaudio codec 33 via anecho canceller 32. Theaudio codec 33 generates an audio encoded transmission signal NTa by encoding (compressing) the supplied audio signal DAmic. Theaudio codec 33 then supplies the audio encoded transmission signal NTa to thecommunication unit 40. In addition, theaudio codec 33 decodes (decompresses) an audio encoded received signal NRa supplied from thecommunication unit 40. Theaudio codec 33 supplies an audio signal DAr obtained by the decoding to a D/A converter unit 34 via theecho canceller 32. The D/A converter unit 34 converts the supplied audio signal DAr into an analog audio signal SAout. The D/A converter unit 34 then supplies the audio signal SAout to thespeaker 14. Thespeaker 14 outputs audio on the basis of the audio signal SAout. - The
communication unit 40 is connected to anetwork 90. Thecommunication unit 40 supplies the signals supplied from thevideo codec 23 and theaudio codec 33 and the signal supplied from the inputimage processing unit 27 to a two-way communication apparatus of a desired person at another end. In addition, thecommunication unit 40 supplies a video encoded received signal NRv directed to the own apparatus to thevideo codec 23, and supplies an audio encoded received signal NRa directed to the own apparatus to theaudio codec 33. - The
control unit 50 is connected with anoperation input unit 51, amemory unit 52, and an externalmemory interface unit 53. Theoperation input unit 51 receives user operations. Theoperation input unit 51 is formed by using a pointing device, a keyboard or the like. When aremote control device 60 having functions of a pointing device, a keyboard or the like is used, theoperation input unit 51 is provided with a receiving unit for receiving a control signal from theremote control device 60. Theoperation input unit 51 generates an operation signal PS according to an operation of the pointing device, the keyboard or the like or on the basis of the control signal received by the receiving unit. Theoperation input unit 51 supplies the operation signal PS to thecontrol unit 50. - The
memory unit 52 is formed by a rewritable nonvolatile memory. Thememory unit 52 stores other end person information on a person at another end with whom to have a conference. - The external
memory interface unit 53 is to enable recording media such as a memory card and the like (not shown) to be connected to the two-way communication apparatus 10. When other end person information and a still image are registered on the recording media, and the recording media are loaded into the externalmemory interface unit 53, it is possible to have a private conference with a person at another end who is not registered in thememory unit 52. It is also possible to transmit a private still image. Further, storing a new program on the recording media makes it possible to update or extend functions of the two-way communication apparatus 10. - The
control unit 50 generates a control signal CT using the operation signal PS generated by theoperation input unit 51, the other end person information registered in thememory unit 52, the information stored on the recording media loaded into the externalmemory interface unit 53, and the like. Thecontrol unit 50 controls each part by the control signal CT to perform videoconferencing with a desired person at another end. - In addition, the
control unit 50 uses the other end person information registered in thememory unit 52 and on the recording media loaded in the externalmemory interface unit 53, and the still images stored in theimage memory unit 26. Further, thecontrol unit 50 controls the operation of the scaler/OSD unit 24 and thedisplay driving unit 28 to display parts of a graphical user interface on thedisplay unit 12. Further, thecontrol unit 50 indicates and selects a part in response to a user operation received by theoperation input unit 51 to allow operation change, various settings and the like in the two-way communication apparatus 10, whereby a graphical user interface is formed. - When the above-described
remote control device 60 has a function of a keyboard, for example, theremote control device 60 has at least a cursor moving key for changing an indicated part by moving a cursor and an enter key for selecting a part indicated by the cursor.FIG. 3 shows an external appearance of theremote control device 60. Incidentally,FIG. 3 represents a case where theremote control device 60 has acursor moving key 61 for moving the cursor in an upward direction, a downward direction, a left direction, and a right direction, and anenter key 62 for selecting a part indicated by the cursor. Thisremote control device 60 has aradio transmission unit 63 for transmitting a control signal indicating an operated key using infrared rays or the like. Incidentally, thecursor moving key 61 includes an upward direction cursor moving key 61 a, a left direction cursor moving key 61 b, a downward direction cursor moving key 61 c, and a right direction cursor moving key 61 d. - In the graphical user interface of the thus formed two-
way communication apparatus 10, one of changing of an indicated part and selection of an indicated part is performed selectively in response to a user operation, and a part operation is enabled in either of cases of using a pointing device and using a keyboard. - In addition, in the two-
way communication apparatus 10, the state of parts is limited to states corresponding only to changing of an indicated part and selection of an indicated part. For example, the state of parts is limited to states of a normal, a focus-in, a push, and a select. The normal represents a state before indication. The focus-in represents a state of being indicated by the pointer or the cursor. The push indicates that a selecting operation is performed. The select represents a selected state after the selecting operation is performed. By thus limiting the state of parts, one of changing of an indicated part and selection of an indicated part can be performed correctly, and even when an operation of inputting a character, a number, or a symbol on the keyboard, for example, is performed, this operation can be disabled. - Further, when a disabled state, that is, a state in which a part is disabled and thus cannot be indicated is provided as a state of the part, the indication or the selection of the disabled part can be prevented.

number input area 125 is to directly input the connection destination information (for example a telephone number, an IP address or the like) of another person when the other person is not registered in the address book. In this case, when the connection destination information of another person is input, a software keyboard is used, as will be described later. - A
dialing button 126 starts a connection using the connection destination information input in thenumber input area 125. - A menu
bar display button 127 is to display a setting menu. The setting menu includes for example an outgoing call setting menu for setting attributes such as a line to be used at a time of an outgoing call, a compression system and the like, an incoming call setting menu for setting attributes of whether to make automatic response or manual response at a time of an incoming call, a general setting menu for setting the name of the own self, a date and time, an audio setting menu, and a network setting menu. - A
video display area 128 displays a picked-up image of the own self while connection to another person is not made. Thevideo display area 128 displays a picked-up image of another person after connection to the other person is established. - A
system status indicator 129 displays the information on the connection destination of the two-way communication apparatus 10 and information on the loading state of recording media and the like. - Operation when operations are performed using the pointing device and operation when operations are performed using the keyboard will next be described individually. Incidentally, description will be made supposing that a pointer indicates a position on the screen when the pointing device is used, and that a cursor indicates a position on the screen when the keyboard is used.
- In the case of using the pointing device, when a user operation is performed to set the pointer Po at a position in the area of the one-
touch dialing list 121 and set the pointer Po in a focus state as shown inFIG. 5A , that is, when a user operation is performed to indicate the one-touch dialing list 121, thecontrol unit 50 makes a pop-updisplay 131 showing information on other persons registered in a one-touch button list, as shown inFIG. 5B . In the pop-updisplay 131, the names and connection destinations of the registered other persons are displayed as the information on the other persons. - When a user operation is thereafter performed to indicate information on a desired person from the pop-up
display 131 by the pointer Po, thecontrol unit 50 makes a pop-upmenu display 132 for the indicated person, and enables only items within the pop-upmenu display 132 to be indicated and sets other buttons and the like in a disabled state to prohibit the other buttons and the like from being indicated. - The pop-up
menu display 132 has acalling button 132 a, a one-touch edit button 132 b, and a one-touch deletion button 132 c. Thecalling button 132 a is to start a connection using the connection destination information of the other person for whom the pop-upmenu display 132 is made. The one-touch edit button 132 b is to edit the information on the other person for whom the pop-upmenu display 132 is made. When the one-touch edit button 132 b is selected, thecontrol unit 50 displays a screen (not shown) for editing the information on the other person to allow a correction, an addition, or a deletion of information on a software keyboard to be described later. Incidentally, when the information is edited, information in the address book is also corrected in such a manner as to be interlocked with the editing of the information for consistency of the information. The one-touch deletion button 132 c is to delete the other person for whom the pop-upmenu display 132 is made from the one-touch dialing list 121. - When the operating key of the pointing device is pushed in a state of the
calling button 132 a being indicated, that is, when thecalling button 132 a being indicated is selected, thecontrol unit 50 determines that a calling operation is performed, and performs a process for starting a connection to the other person for whom the pop-upmenu display 132 is made. When a video signal of the other person is supplied after the connection, thecontrol unit 50 displays a picked-up image of the other person in thevideo display area 128. - When the operating key of the pointing device is pushed in a state of the
number input area 125 being indicated, that is, when thenumber input area 125 being indicated is selected, thecontrol unit 50 displays asoftware keyboard 141 as shown inFIG. 5C . Thesoftware keyboard 141 can be switched between a kana input screen and an alphanumeric/symbol input screen, for example. By focusing the pointer Po on the position of a desired character or symbol and pushing the operating key, the character or symbol on which the pointer Po is focused can be input. - When an operation of indicating and selecting the

By moving the cursor Ks to the position of a desired character or symbol or the like and operating the enter key, the character or symbol or the like indicated by the cursor Ks can be input. Then, the operation of the software keyboard is ended. - When an operation of indicating and selecting the
dialing button 126 is performed after completion of input of the connection destination information of another person using the software keyboard, thecontrol unit 50 performs a connection starting process using the connection destination information input in thenumber input area 125. - When the upward direction cursor moving key 61 a is operated while the cursor Ks is at the position of the address book button as shown in
FIG. 6A , thecontrol unit 50 displays the cameraadjustment frame display 151 as shown inFIG. 6F , and indicates the cameraadjustment frame display 151 by the cursor Ks. Further, when theenter key 62 is operated in a state of the cameraadjustment frame display 151 being indicated, that is, when the cameraadjustment frame display 151 being indicated is selected, thecontrol unit 50 enables adjustment of an image pickup direction and an angle of view of theimage pickup unit 11 using the cameraadjustment frame display 151. In this case, when the cameraadjustment frame display 151 is selected, the cursor Ks is set at the position of one of theupward direction display 151 a, theleft direction display 151 b, thedownward direction display 151 c, and theright direction display 151 d, for example. In addition, one of theupward direction display 151 a, theleft direction display 151 b, thedownward direction display 151 c, theright direction display 151 d, thewide display 151 e, and the tele display 151 f is allowed to be indicated according to an operation of a key of thecursor moving key 61. - When a user operation of indicating and then selecting the
upward direction display 151 a provided in the cameraadjustment frame display 151 is performed on theremote control device 60, thecontrol unit 50 controls theimage pickup unit 11 to perform a tilting operation for changing the image pickup direction upward. When a user operation of indicating and then selecting thedownward direction display 151 c is performed on theremote control device 60, thecontrol unit 50 controls theimage pickup unit 11 to perform a tilting operation for changing the image pickup direction downward. - When a user operation of indicating and then selecting the
left direction display 151 b provided in the cameraadjustment frame display 151 is performed on theremote control device 60, thecontrol unit 50 controls theimage pickup unit 11 to perform a panning operation for changing the image pickup direction to the left. When a user operation of indicating and then selecting theright direction display 151 d is performed on theremote control device 60, thecontrol unit 50 controls theimage pickup unit 11 to perform a panning operation for changing the image pickup direction to the right. - Further, when a user operation of indicating and then selecting the
wide display 151 e is performed on theremote control device 60, thecontrol unit 50 controls theimage pickup unit 11 to reduce the zoom magnification and thereby increase the angle of view. When a user operation of indicating and then selecting the tele display 151 f is performed on theremote control device 60, thecontrol unit 50 controls theimage pickup unit 11 to increase the zoom magnification and thereby display an enlarged subject. - Thus, it is possible to operate or set the two-
way communication apparatus 10 by changing an indicated part by moving the cursor Ks according to a user operation of thecursor moving key 61 and then selecting the indicated part by theenter key 62. - The operation that can be performed using either of the pointing device and the keyboard is not limited to the operation for performing two-way communication with a desired other person using an address book as shown in
FIGS. 5A to 5D andFIGS. 6A to 6F. Menu selecting operation will next be described as operation that can be performed using either of the pointing device and the keyboard. -
FIGS. 7A, 7B , 7C, and 7D show menu selecting operation using the pointing device. In the case of using the pointing device, when the pointer Po is set at a position in the area of the menubar display button 127 and set in a focus state, and thereafter a push operation is performed, that is, when a user operation of selecting the menubar display button 127 is performed, thecontrol unit 50 makes amenu bar display 200 in place of the one-touch dialing list 121, as shown inFIG. 7A . - The
menu bar display 200 includes acamera control button 201, a status andinformation button 202, astill image button 203, a recordingmedia load display 204, and asetting button 205. Thecamera control button 201 is to display the cameraadjustment frame display 151 or the like as shown inFIG. 5D so that the image pickup direction and the angle of view of theimage pickup unit 11 can be adjusted by using this display. The status andinformation button 202 is to display information on the two-way communication apparatus 10, the status of a line during communication, and the like. Thestill image button 203 is to store an image during communication as a still image on the recording media loaded in the externalmemory interface unit 53, and to display a still image stored on the recording media. The recordingmedia load display 204 makes it possible to determine whether recording media are loaded in the externalmemory interface unit 53. Thesetting button 205 is to make various settings of the two-way communication apparatus 10, settings for communication, screen display settings, and the like. - When a user operation for setting the pointer Po at a position of the
menu bar display 200 as shown inFIG. 7B is performed, thecontrol unit 50 makes a pop-updisplay 210 describing functions of thecamera control button 201, the status andinformation button 202, thestill image button 203, the recordingmedia load display 204, and thesetting button 205. - When a user operation is thereafter performed to set the pointer Po at the position of one of the buttons in the pop-up
display 210 and set the pointer Po in a focus state, that is, when a user operation is performed to indicate one of the buttons by the pointer Po, thecontrol unit 50 makes a pop-up menu display for the indicated button, and enables only items within the pop-up menu display to be indicated and sets other buttons and the like in a disabled state to prohibit the other buttons and the like from being indicated. For example, when thesetting button 205 is indicated, a pop-upmenu display 220 for thesetting button 205 is made, as shown inFIG. 7C , and the other buttons and the like are set in a disabled state. - The pop-up
menu display 220 includes an incomingcall setting button 221, adevice setting button 222, anaudio setting button 223, anetwork setting button 224, a communicationmode setting button 225, anadministrator setting button 226, and adisplay setting button 227. The incomingcall setting button 221 is to set an operation at a time of an incoming call. Thedevice setting button 222 is to make a time setting and device-related settings for indicator display and the like. Theaudio setting button 223 is to make audio-related settings for the microphone and the like. Thenetwork setting button 224 is to make network-related settings and settings related to a call control protocol such as SIP (Session Initiation Protocol) or the like. The communicationmode setting button 225 is to select a compression system for video and audio. Theadministrator setting button 226 is used when setting is made on setting items limited to an administrator. Thedisplay setting button 227 is to set image quality and a display mode. - For example, when the pointer Po is set at the position of the
device setting button 222 in the pop-upmenu display 220 and is set in a focus state, and thereafter a push operation is performed, that is, when a user operation of selecting thedevice setting button 222 is performed, thecontrol unit 50 makes a devicesetting menu display 230 as shown inFIG. 7D to allow setting on various items. - Thus, it is possible to make various settings for the two-
way communication apparatus 10 by changing an indicated part by moving the pointer Po according to a user operation and then selecting the indicated part by operating the key of the pointing device. - Menu selecting operation using the keyboard will next be described with reference to
FIGS. 8A, 8B , 8C, and 8D. On a first top screen, the cursor Ks is set at the position of theaddress book button 123, for example. When the downward direction cursor moving key 61 c is operated, thecontrol unit 50 moves the cursor Ks from theaddress book button 123 to the menubar display button 127 to indicate the menubar display button 127. When theenter key 62 is thereafter operated, thecontrol unit 50 determines that a user operation of selecting the menubar display button 127 is performed, and makes themenu bar display 200 in place of the one-touch dialing list 121, as shown inFIG. 8A . - When the upward direction cursor moving key 61 a is operated while the
menu bar display 200 is made, thecontrol unit 50 moves the cursor Ks to a position within themenu bar display 200, and makes the pop-updisplay 210 describing functions of buttons and displays as shown inFIG. 8B . In addition, thecontrol unit 50 sequentially changes and indicates the buttons and displays provided within themenu bar display 200 according to an operation of the upward direction cursor moving key 61 a or the downward direction cursor moving key 61 c. - When a predetermined time has passed after the cursor Ks is set at the position of a desired button, or when the cursor Ks is set at the position of a desired button and the
enter key 62 is operated, thecontrol unit 50 makes a pop-up menu display for the button at which the cursor Ks is positioned. For example, when the cursor Ks is at the position of thesetting button 205, thecontrol unit 50 makes the pop-upmenu display 220 for thesetting button 205 as in the case ofFIG. 7C . When the right direction cursor moving key 61 d is operated while the pop-upmenu display 220 is made, thecontrol unit 50 moves the cursor Ks to the position of for example the first incomingcall setting button 221 in the pop-upmenu display 220 as in the case ofFIG. 7C . - When the upward direction cursor moving key 61 a or the downward direction cursor moving key 61 c is operated with the cursor Ks positioned in the pop-up
menu display 220, thecontrol unit 50 moves the cursor Ks according to the user operation to sequentially and cyclically change and indicate the buttons within the pop-upmenu display 220. - When the
enter key 62 is operated while the cursor Ks is positioned at thedevice setting button 222, that is, when an operation of selecting thedevice setting button 222 is performed while thedevice setting button 222 is indicated by the cursor Ks, thecontrol unit 50 makes the devicesetting menu display 230 as shown inFIG. 8D to allow setting on various items. - Thus, since the
menu bar display 200, the pop-upmenu display 220, the devicesetting menu display 230 and the like are hierarchically displayed, various operations and settings can be made efficiently without occupying a large display area on the screen. - A call screen shown in
FIG. 9 , for example, is displayed on thedisplay unit 12 while a two-way communication is performed with a desired other person after operation and setting are performed using the pointing device or the keyboard as described above. Incidentally,FIG. 9 shows a state in which themenu bar display 200 is displayed. - The call screen includes a plurality of display screens. A
parent screen 300 displays one of an image of the own self, an image of another person, a still image recorded on the recording media, a still image transmitted from the other person, and the like. Alternatively, these images are displayed in a changeable manner. Achild screen 310 makes a screen display different from that of theparent screen 300, for example. Incidentally,FIG. 9 shows astill image 301 displayed as theparent screen 300, and anown self image 311 and anotherperson image 312 displayed as thechild screen 310. The above-described camera adjustment frame display is displayed together with the display of theown self image 311 so that the image pickup direction can be adjusted while the own self image is picked up. - The call screen also includes a
disconnection button 321, amicrophone switch button 322, arecording media display 323, acommunication quality display 324, amicrophone level display 325, and a call elapsedtime display 326. Thedisconnection button 321 is to end a call. Themicrophone switch button 322 is to change a microphone function to an on state or an off state. The recordingmedia load display 323 is similar to the above-described recordingmedia load display 204. The call elapsedtime display 326 indicates a call elapsed time. - The
communication quality display 324 enables a communication quality state to be determined. Thecommunication unit 40 measures a packet error rate, for example. Thecommunication unit 40 supplies a result of the measurement to thedisplay driving unit 28 or thecontrol unit 50 for display control of thecommunication quality display 324. Thecommunication quality display 324 is a bar display divided into a red bar, a yellow bar, and a green bar, for example. When the packet error rate is good, all of the red bar, the yellow bar, and the green bar are displayed. When the packet error rate is deteriorated, the number of displayed bars is reduced; for example the red bar and the yellow bar are displayed. When the packet error rate is further deteriorated, only the red bar is displayed. When the packet error rate is further deteriorated, no bar is displayed. The number and the colors of the displayed bars are thus controlled according to the communication quality state, whereby the communication quality state can be determined easily. - The
microphone level display 325 indicates the level of a microphone signal when the microphone function is in an on state. Using thismicrophone level display 325, a distance to themicrophone 13 is increased or decreased or the gain of the microphone signal is adjusted so as to attain an appropriate level of the microphone signal. Thus, an audio signal having an appropriate signal level can be transmitted to the destination of another person. Incidentally, thedisconnection button 321 and themicrophone switch button 322 of the call screen can also be indicated or selected by using the pointing device, the keyboard and the like. Incidentally, the call screen includes a screenlayout setting button 207 for setting a screen layout in themenu bar display 200. - In the operation for performing two-way communication with a desired other person using an address book and the menu selecting operation, the one-
touch dialing list 121, the pop-up menu displays 132 and 220, themenu bar display 200, the pop-updisplay 210 and the like displayed on the screen are displayed transparently. Such transparent display enables a screen in a lower layer to be distinguished even when the one-touch dialing list 121, the pop-up menu displays 132 and 220, themenu bar display 200, the pop-updisplay 210 and the like are displayed. - As described above, when one of changing of an indicated part and selection of an indicated part is performed selectively in response to a user operation, even in the case of using either the pointing device or the keyboard, the part of the graphical user interface can be operated similarly, and thus the two-way communication apparatus can be operated or set easily. In addition, since a graphical user interface when the pointing device is used and a graphical user interface when the keyboard is used do not need to be provided separately from each other, graphical user interface design can be performed efficiently, and it is therefore possible to prevent the lengthening of a design period and an increase in the number of man-hours for design. Further, it becomes possible to provide the two-way communication apparatus at a low cost.
- It is to be noted that the parts used in the above-described graphical user interface, the arrangements of the parts, the operations when the pointer Po or the cursor Ks is operated are illustrative, and are of course not limited to the above-described forms.
- It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
